Validated, DWI Compliant UV Systems For Drinking Water Disinfection

A number of Water Treatment Works across the UK are now investing heavily in Ultraviolet technology, as the threat of chlorine resistant parasites such as Cryptosporidium and Giardia continues to pose a serious risk to water companies and their customers.

Cryptosporidium outbreaks are now becoming increasingly frequent in all areas of the water industry.
However, due to recent successes with UV systems following a number of high profile outbreaks at drinking water sites worldwide, the ability to effectively protect against Cryptosporidium is now becoming a reality for water treatment engineers worldwide.

In the UK, this reality has become further endorsed by the Drinking Water Inspectorate (DWI), who have issued their guidelines for UV operation and system selection to the UK water industry.

A key feature of their guidance is UV system validation. Validation refers to a series of 3rd party testing to ensure the performance of an Ultraviolet system design under a range of operating environments.

The DWI guidance states: “DWI recommends any water company considering the use of UV irradiation for the disinfection of public water supplies to consult the US EPA Ultraviolet Disinfection Guidance Manual (UVDGM)”

As an industry expert with considerable experience in supplying US EPA Validated UV systems for Cryptosporidium protection, atg UV are well placed to support and advise all drinking water companies on the application of the DWI guidelines including validation, log reduction, RED Dose, installation, upgrades and retrofits, industry regulation and future product development.

ave designed and developed a large range of UV systems specifically for municipal drinking water, waste water and grey water re-use applications that are fully compliant with the requirements of the Drinking Water Inspectorate 2010 guidelines.

atg UV’s product range offers fully validated and 3rd party tested US EPA UVDGM systems that deliver a 1 - 5 log reduction of Cryptosporidium for flows as small as 10 m3/hr to over 5000 M3/hr within a single high output, small footprint, medium or low pressure system.
